What is some of your guy's problem with having more information?
You'd really rather be ignorant, and speculate about/vote for games in surveys that are actually already in development (seen this for many games that were actually secretly in development like Majora's Mask 3D), than live with the knowledge over a longer period of time? It's so difficult that you'd willingly chose ignorance?
This is why we can't have nice things.
I'm happy Capcom told me about RE Make 2 in 2015. Because I know they heard the fans wishes. Even if it ended up being canceled, at least I knew they gave it a shot. And that's all I can really ask of them.
Personally, I didn't mind that Kingdom Hearts III was announced too early, at that time (back in 2013, before the game was announced) I REALLY wanted confirmation that a new home console KH game was in development, even though I knew I would have to wait years and years to play it.
